ARIZONA BF by BIRKENSTOCK has a simple yet iconic design that has made it a highly popular style for decades, and is what many consider to be the epitome of a BIRKENSTOCK sandal. The ARIZONA is a unisex sandal featuring a two-strap upper that can be adjusted using the sturdy buckles, a traction patterned sole, and the classic BIRKENSTOCK cork latex footbed that will support your feet, with the anatomically moulded design guiding them into a natural position. The BF stands for Birko-Flor, which is one of BIRKENSTOCK's high quality synthetic alternatives to leather that is exceptionally durable and easy to clean, and has a smooth leather like finish. Product care: Please note, water can damage the cork and dissolve the glue/sealant. If your shoes get wet, dry them slowly and away from direct heat.
